This is what brought me back but everybody is different you see Dom
pct will be big, and it could take 2-3 attempts, but its worth it.

aromasin- 12.5---12.5---12.5---12.5---12.5---12.5---12.5
clomid- 150---100---100---100---50---50
nolvadex- 60---60---60---40---40---40---40---40

hcg- 1000iu everyday for a month then 500iu every 2nd day for a month

When I come off I usually run creatine and/or l-carnitine and l-arginine and a test booster for maintenance. The best option really talk to Don from bloodworks, seems like he's been helping many, well worth the investment in my opinion. Do you feel your nuts have shrinked? I'd start with HCG asap. As far as PCT protocols go they are all similar (lots of HCG when coming off then Clomid and Nolva), and like Banga said you should run it twice as long. Honestly I don't think you did permanent damage, but will need a little longer to recover. Again blood tests is the safest way.
PS: Don't take my advice, use the information to help your research and find a professional.

I have no scientific data to back what I'm going to say right now, so i would highly suggest reading your ass off and see what you can find out.
But me personally, i feel that basically you've been blasting for 12 months. Even when running just test e at 750mg per week, i personally consider that a blast, plus you've added superdrol and npp to the mix over the year.
I would drop your dose back to 250mg per week and 'cruise' for a couple of months while starting to run hcg in a medium range dose per week (around the 1000iu mark). Then after a few months of that look towards a power pct product and run it for double the average pct time frame.
After 12 months on why do you want to come off? At the age of 25, you have potentially done yourself some damage long term mate. You really need to ween yourself off and have bloods done every two weeks id suggest if you plan to come off and stay off. Bloods will show your hormone levels and help you adjust your pct accordingly.

I reckon your best bet would be to talk to Don from bloodworks get your bloods done and get advice from a professional. I was on high doses of test n bold for 8-9 months last year he had me up and running in no time best I've ever bounced back in 10years of juicing and I hadn't done any hcg throughout the whole cycle and didn't add any in my pct

Ouch.,

I'd start running HCG towards the end of your cycle and then clomid n tamoxifen when you finish once the ester has cleared.

Expect to drop some tho. Eat well train hard n you should keep a good amount. Just prepare for the drop in test n the associated down feelings after being on for so long.

That's just my opinion guys on here might have different experiences n ideas so just research n see what's best
